Convert a history or note to an activity

We can convert an Outlook e-mail to an activity IN OUTLOOK, but when the Outlook e-mail becomes a part of the contact's history, it cannot be converted to an activity within ACT!. Why can't we convert that history into an activity?

Also, sometimes my notes on a contact wants to become a reality, why can't this be converted to an activity also?

A right-click context menu entry to convert a note/history into an activity wouldn't be a bad idea.
